Facebook doubled its user base since 2012

It is quite surprising when the Chief Executive of Facebook Mark Zuckerberg unveiled the number to his followers in a Facebook post. “It's an honor to be on this journey with you,” he wrote. 

Well, the number would spin your heads for a moment which is… 2 billion. Facebook said that they are its regular customers of this flagship service; the user base is bigger than the population of any single country, and of six of the seven continents. It represents more than a quarter of the world's 7.5 billion people. 

The number of users exceeds the population of any single country, and of six of the seven continents. Facebook construed that a monthly active user as a registered Facebook user who logged in and visited Facebook via its website or a mobile service, or used its messenger application for the past 30 days.

To increase penetration rates in developing nations, Facebook has rolled out pared-down versions of its apps that use less data, and it has been developing solar-powered drones to extend internet connectivity around the planet.
